LUXOSTAT.

Specification of Letters Patent.

Patented Feb. 11, 1919.

Application led April 25, 1917. Serial N0. 164,538.

To all whom, 'it may concern:

Be it known that I. WALTER J AMES Han- VEY, a subject of the King of Great Britain, and resident of the city of Columbus, in the State of Ohio, in the United. States of America, have invented certain new and useful Improvements in Luxostats, as described in the following specification and illustrated in the accompanying drawings, that form part of the same.

The principal objects of this invention are, to devise a means for utilizing to the fullest extent the effective qualities of the suns rays and to simplify the applicati'n of light in therapeutic and ophthalmic and other work, controlling and regulating the quantity, quality and composition of the light to suit the various requirements.

The principal feature of the invention consists in the novel construction and arrangement and operation of apparatus, whereby the suns rays are intercepted by a reflecting surface and directed to an adjustable converging surface which may be regulated to suit varying conditions and from said surface the beam formed by the concentrated rays is directed to a suitable means for separating the constituents of the light.

In the accompanying drawings, Figure 1 is a plan diagram showing apparatus arranged in accordance with this invention and adapted to maintaina continuous concentration of light rays.

Fig. 2 is a vertical sectional detail of my improved adjustable concentrating device.

Fig. 3 is a side elevational view of one of Ehe automatically adjustable reflecting memers.

Fig. 4: is an elevational diagram further illustrating the lan diagram shown in Fig. 1 and showing t e manner of receiving and handling the light rays.

The latent energy and therapeutic qualities of light are well known to science and up to the present very little practical use has been made of such qualities and it is the purpose of thisinvention to produce means for effectively utilizing these valuable qualities contained in the suns rays. In order to accomplish this result it is first necessary to arrange reflecting apparatus, time controlled, in such a manner as to retain a con stant relation with the rays of light and in conjunction with said reiecting apparatus to devise an e ing the reiiecte Ipays.

ctive means for concentraty I find in practice the desired result may 'be accomplished by an arrangement of apparatus as herein shown and described. The apparatus is of course preferably arranged under cover and is placed in a glass housing through which the light rays readily' pass.

A reflecting member 1 is supported from a pedestal 2 in a central position withinthe light room, said reflector being carried upon a transversely rotatable f member, which member is operated by means of a suitable clock mechanism operating a vertical spindle 3 having a pinion i at the end meshing with the geared quadrant 5 on the pivotal 70 arm 6 on the outer end of which the mirror is pivotally supported.

The clock mechanism is adapted to eiect the swinging of the pivotal arm carrying the mirror through an arc of substantially a half circle and the mirror is tilted upon its pivotal connection with the arm coincident with its rotating movement by means of a strut 7 pivotally secured at one end to the supporting pedestal 2 and at the lother end 80 to the lower portion of the mirror so that when the mirror is in its central position it will be tilted outwardly from the bottom and as it swings in either direction laterally the strut which remains of a constant length g5 draws the bottom inwardly, thus rectifying the angle of the mirror.

The strut 7 is preferably formed of telescoping parts for the purpose of adjustment but when in use the parts are rigidly clamped together. The rays of light reflected from the mirror 1 are directed to a concentrating member 8 which is here shown in the form of a bowl containing a suitable reflecting duid. The bowl 8 is preferably 95 supported upon a needle point bearing 9 within an encircling bowl 10 and a suitable supporting fluid is contained within the bowl 10 to support and centralize the concentrator 8. i

The bowl 10 is carried upon a rotatable spindle 11 journalcd in the base 12. This spindle is operated by means of a suitable motor 13 arrangcdwithin the base and the motor is operatively connected with vthe 105 spindle by means of an adjustable friction disk drive 14, the roller 15 of the roller friction disk drive being carried upon the spindle 16 which is adapted to be adjusted by means 0f the lever 17.

The rotation of the spindle l1 and the bowl 10 causes the concentrator bowl 8 to concurrently rotate and as the speed of rotation is increased or diminished the surface con'tour of the reieeting fluid within the bowl 8 will be altered in an increasing or diminishing concavity.

The rays of light from the mirror l are directed upon the concave reflecting surface of the concentrator 8 and are there concentrated and directed upwardly on to the adjustable reflecting member 18 which is of substantially the same construction and operating in a similar manner to the retlector l, except that the rei-lector is required to be tilted out at the top and in at the bottom in the central or mid-day posit-ion and to be swung inwardly at the top as it moves to either side position. To accomplish this ef. feet the strut connection 18a is pivotally connected at one end to the back of the relector adjacent to the top and at the other end to a rigid extension from the pedestal.

The reflector 18 is so arranged in relation to the concentrator as 'to receive the beam of light and direct it to a. suitable screen 19 or separating member arranged upon the pedestal 20. This screen is preferably an adjustable prism and the light beam directed thereupon is there split up into its various constituents. Other forms of screens to suit the purpose for which the light is being concentrated may be used,` as desired.

The apparatus is herein shown and described as having the light rays reflected on to the concaved fluid reflector but it must be understood that the said fluid reflector may be utilized to converge the rays falling Copies of this patent may be obtained for ve cents each, by addresiingth i Washington, D.

thereon direct and it must also be understood that a, dissecting element may be introduced at any desired point to eliminate any particular class of ra What I claim as my invention is 1. A reiiector member, comprising, a rotatable bowl receptacle adapted to be -rotated upon its axis, means for rotating said bowl at varying speeds, an inner bowl rotatably supported upon the axis of the outer bowl and containing a suitable reflecting fluid, and a supporting Huid medium arranged between the inner and outer bowls.

2. A. reflector member, comprising, a ro tatable bowl, a shaft secured to said bowl, a disk mounted on said shaft, an adjustable rotatable member operatively engaging said disk and adapted to rotate the same, means for moving said adjustable member toward and from the center of said disk, a supporting fluid arranged within said bowl, and an inner bowl journaled within the aforesaid bowl on 'a point in alinement with the axis hereof and containing a suitable reflecting 3. A reflector member, comprising, a bowl supported upon a. vertical axis'and adapted to rotate on said axis, mechanical means` for rotating said bowl at varying speeds, an inner bowl having a needle point supported arranged in alinement with the axis of the outer bowl and containing a suitable reflecting fluid. and a supporting fluid :1r-

ranged between said bowls and supporting the lnner bowl.
